Summary
Mobile phones using Global System for Mobile Communication (GSM) technology have not caused widespread hearing aid interference as initially feared. However, eliminating interference from direct phone-to-hearing aid contact remains a challenge.
Area of Science:
- Audiology
- Electromagnetic Compatibility
- Telecommunications Engineering
Background:
- Overview of European experiences with Global System for Mobile Communication (GSM) mobile phones and hearing aids.
- Initial concerns regarding widespread hearing aid interference from GSM technology.
- Development of the International Electrotechnical Commission (IEC) 118-13 standard for interference measurement.
Purpose of the Study:
- To present the European Hearing Instrument Manufacturers Association's perspective on GSM mobile phone interference with hearing aids.
- To evaluate the justification for initial fears of widespread interference.
- To discuss existing standards and ongoing research in the field.
Main Methods:
- Review of past and current European experiences with GSM mobile phones and hearing aids.
- Description of the background and rationale for the IEC 118-13 standard.
- Analysis of reported interference issues and current research on measurement standards.
Main Results:
- Initial fears of widespread interference problems for hearing aid users appear largely unjustified.
- The IEC 118-13 standard provides a basis for measuring electromagnetic interference.
- Complete elimination of interference from direct contact between hearing aids and mobile phones has not yet been achieved.
Conclusions:
- While widespread interference has not materialized, direct contact issues persist.
- Ongoing work on measurement standards for near-field situations is crucial.
- Further research and standardization are needed to address remaining interference challenges.
